Abstract
Combustion of chromium powder in SHS reactors is examined. It is shown that the maximum temperature in the central part of the powder samples is highe r than the adiabatic temperature. The observed phenomenon is due to the non -one-dimensionality of the combustion front. Overheating of the central par t leads to melting of the product and a decrease in the degree of conversio n, which should be taken into account in nitration of samples of large diam eter.
